Definition of powder metallurgy in English:

noun

Originally, niobium metal was produced by powder metallurgy methods which involved high temperature vacuum sintering and carbon reduction.

For certain products, such as those produced by powder metallurgy or from small ingots, it may be possible to significantly alter the distribution of insoluble particles.

Alloys prepared by powder metallurgy, in which often very large amounts of alloying elements are incorporated, naturally reach much higher strengths, usually at the expense of ductility and stress corrosion resistance.
